WRA0505S-1WR2: 1W DC/DC Converter, 2:1 Input, 5V Dual Output, SIP

The WRA0505S-1WR2 is a compact, dual-output 1W DC/DC Converter from Mornsun, designed for low-power, isolated applications in industrial control, instrumentation, and communication systems. This converter features a wide 2:1 input voltage range of 4.5VDC to 9VDC, making it highly flexible for systems with a nominal 5V supply that may experience voltage fluctuations. It provides a precisely regulated 5VDC dual output with a maximum current of 100 milliamperes (100mA) on each rail, ideal for powering sensitive analog circuitry such as operational amplifiers and data converters.

The module is engineered for reliability, offering 1.5kV isolation to protect downstream components and ensure noise immunity. Its wide operating temperature range of -40 C to +85 C guarantees performance in harsh industrial environments. The inclusion of a Remote On/Off feature allows for external control, enhancing system power management capabilities. Packaged in a compact 8-SIP (Single In-line Package) for through-hole mounting, the WRA0505S-1WR2 is a space-saving and efficient solution, boasting an efficiency of 73%.
